Smart Atmospheric Monitoring: Low-Cost DOAS Technology

What is the DOAS system?

Our DOAS (Differential Optical Absorption Spectroscopy) system is an innovation developed by Salvadoran scientists to monitor atmospheric pollutants with laboratory precision, but at a revolutionary cost. Using advanced optical technology, it detects gases such as sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and ozone (O₃) in real time, even at minimal concentrations. Unlike traditional systems, our modular design reduces installation and maintenance costs by up to 60%, democratizing access to critical data for industries, governments, and communities. It’s not just a measurement tool: it’s a step toward a future with clean air and healthier cities.
